    Snail Sex Tape
    In this episode, we consider a creature we often don’t think much about—the snail. And not just snails, but their sex lives. Which, as it turns out, is epic. There is persuasion and subterfuge, spaghetti penises and co-copulation. And this very surprising habit—erm kink—of making tiny arrows (actually!) and stabbing each other with them. Known as a “love dart,” these limestone daggers aren’t just a strange trick of nature—they have a deep evolutionary purpose.  Special thanks to Menno Schilthuizen and Aaron Chase.EPISODE CREDITS:  Hosted by - Molly Webster Reported by - Molly Webster Produced by - Mona Madgavkar, Annie McEwen, Molly Webster Sound design contributed by - Mona Madgavkar, Annie McEwen Fact-checking by - Diane A.

    Black Box
    In this episode, first aired in 2014, we examine three very different kinds of black boxes—spaces where we know what’s going in, we know what’s coming out, but can’t see what happens in-between. From the darkest parts of metamorphosis to a sixty-year-old secret among magicians, and the nature of consciousness itself, we shine some light on three questions. But for each, we contend with an answerless space, leaving just enough room for the mystery and magic, always wondering what’s inside the Black Box. EPISODE CREDITS:  Reported by Tim Howard and Molly Webster Produced by Tim Howard and Molly Webster EPISODE CITATIONS: Radio Show: ABC's Keep Them Guessing (https://tinyurl.com/9r9zmftr)LATERAL CUTS: Last year we shared a story on our feed about butterfly researcher Dr. Martha Weiss, and how she befriended a little boy on the other side of the world who wanted to do his own caterpillar memory study. Martha’s daughter Annie Rosenthal captured the whole adventure on tape and produced a gorgeous audio feature, “Caterpillar Roadshow,” which was first published in the audio magazine Signal Hill.  You can find it on our feed (https://zpr.io/xPdAYXFUMr4s) –or on Signal Hill’s website.

    Gray's Donation
    Before he was even born, Sarah and Ross Gray knew that their son Thomas wouldn’t live long. But as they let go of him, they made a decision that reverberated through a world that they never bothered to think about. Years later, after a couple of awkward phone calls, they go on a quest and manage to meet the people and places for whom Thomas’ short life was an altogether different kind of gift. We originally made this story back in 2015, but we wanted to play it again because we love that it brings a view of science that is redemptive, tender, and unexpected. Since we first released this episode, Sarah Gray wrote a book called A Life Everlasting (https://zpr.io/GVYisRaqe9d6), it’s a memoir about Thomas that dives into the world of organ donation and medical science. She’s also written a beautiful short story about shame called The Lacemaker Fairy Tale (https://zpr.io/Li5BMtfHmf92). And, right now she’s working on a script for a movie called Raincheck.EPISODE CREDITS: Reported by - Jad Abumrad with help from - Latif NasserLATERAL CUTS - The Cathedral (https://radiolab.org/podcast/cathedral) The Immortal Life of Henrietta Lacks (https://radiolab.org/podcast/the-immortal-life-of-henrietta-lacks)  Signup for our newsletter!!

    Time is Honey
    In the early 2000s, Sunil Nakrani felt stuck. Back then, websites crashed all the time. When Sunil noticed this, he decided he was going to fix the internet. But after nearly a year of studying the architecture of the web, he was no closer to an answer. In desperation, Sunil sent out a raft of cold emails to engineering professors. He hoped someone, anyone, could help him figure this out. Eventually, he learned that the internet could only be fixed if he paid attention to the humble honeybee. This is the story of the Honeybee Algorithm: How tech used honeybees to build the internet as we know it.Special thanks to John Bartholdi, John Vande Vate, Sammy Ramsey, James Marshall, Steve Strogatz, Duc Pham, and Heiko Hamann.We found out about this story thanks to our friends at AAAS, who run the one and only Golden Goose Awards. The award goes to government funded science that sounds trivial or bizarre, but goes on to change the world. The Honeybee Algorithm won a Golden Goose Award back in 2016 (https://zpr.io/ePxaaYja6YF4). Thank you to our friends there: Erin Heath, Gwendolyn Bogard, Valeria Sabate, Joanne Padron Carney, and Meredith Asbury. EPISODE CREDITS: Reported by - Latif Nasserwith help from - Maria Paz GutiérrezProduced by - Maria Paz Gutiérrez, Annie McEwen and Pat Waltersand Edited by  - Pat WaltersEPISODE CITATIONS:Videos - Golden Goose Award video about 2016 winners (https://zpr.io/eXwTJKGL6F8S)Books -The Wisdom of the Hive: The Social Physiology of Honeybee Colonies (https://www.hup.harvard.edu/books/9780674953765) by Thomas D.
